Welcome to gimp-forums.
First one: Where to put scripts and plugins. What you did is ok, but not recommended. The best location is in your Gimp Profile C:\Users\your-name\.gimp-2.8\scripts for a script something.scm and C:\Users\your-name\.gimp-2.8\plug-ins for something.py or .exe or .dll
Scripts do not provide a preview whereas a plugin might. That particular script is old c.2007 What it does do, is add two layers 'fix-shadows' 'fix-highlights' and if you make the respective layer active (click on it in the layers dialog) you can then adjust the opacity which corresponds to the values you used in the script.

detached the layers dialog to make it easier to see.
I am sure there are better tools somewhere, someone is sure to recommend a plugin.
edit: You might want to look at this reference: https://www.gimp.org/tutorials/Luminosity_Masks/
and remember, Gimp is not PS forget about PS methods, Gimp has its own ways and a steep learning curve, but the end result will be the same, it depends on you.
